The National Geological Repository stores material from samples that are routinely collected from the seabed during the ‘s (MCA) Hydrographic Instruction (HI) (CHP) surveys. Seabed sampling is conducted on an approximately 5 km grid with at least one sample being taken in each major textural area identified. All samples are retained and forwarded to the BGS.
Information on the samples is logged in H575 sample forms using the Nautical Classification and Folk Classification schemes. This information goes into the production of nautical charts at the (UKHO). The H575 forms are also sent to the BGS and archived in the National Geoscience Data Centre (NGDC) and MEDIN Data Archive Centre.
Sample and data access
The sample material and data are a resource that is openly available for further analysis.
- Contact thecontact the Core Store at BGS Keyworthto arrange a visit to view or sample the material
- Locations and sample data will be available from theoffshore GeoIndexin the future: in the meantime, to access the data, you cansend an emailwith the required HI survey numbers or area(s) of interest
- The associated multibeam backscatter data are available from theoffshore GeoIndex
- Multibeam bathymetry data is available from the
Deposit samples
We also have guidance for depositing MCA CHP samples.
